We introduce the axiomatic theory of Spherical Occlusion Diagrams as a tool to study certain combinatorial properties of polyhedra in $\mathbb R^3$, which are of central interest in the context Art Gallery problems for polyhedra and other visibility-related problems in discrete and computational geometry.
